Light, diffraction and interference 2 closely related to the previous questions, with the wavelets superimposing, the geometry involving the wavelength of the light and in relation to slit width and.
The diffraction of x-rays as they pass through a substance, usually forming an interference pattern that can be captured on film and used to analyze the internal structure of the substance. This lesson explores diffraction as one of the many behaviors of waves learn how diffraction occurs in sound and light waves and how it is. Purpose: the aim of doing this experiment was to examine diffraction and interference effects of light passing through various apertures, and use the diffraction patterns obtained by single and double slit apertures to find the wavelength of the light source used. Interference of light the modification in the distribution of light energy due to superposition of two or more waves is called interference of light conditions for interference light source should be monochromatic light source should be coherent mean they should not be independent but should.
